As you will see your link is http://www.peoplestring.com/?u=username. Your username is the name you use to log into PeopleString. Please read the suggestion under your link which is also provided below:

"For best results, we suggest you copy and paste this link into emails that you send from your regular email address. Your deliverability will be higher and your contacts will more likely recognize your email address and accept your invitation."

Optional Referral LinkIf you would like your prospect to immediately be a "friend" in the PeopleString Social site, then make a simple modification to your referral link by replacing the "u" after the question mark with a "f" (for friend).

Thus your link would be http://www.peoplestring.com/?f=usernameBoth links ("u" and "f") will work equally well, it is just a choice you can make as to which one you use.
